What Is the Project Triangle?

The so-called project management triangle refers to the interaction between the three factors of scope, time and cost in project management.

Project Management Triangle

The project as a whole, in order to make all aspects of resources coordinated, must be particularly familiar with the concept of the project triangle. In the scope of the project triangle, in addition to considering the requirements for the direct results of the project, it is also necessary to consider the human resource management, quality management,

The project triangle emphasizes the close relationship between these three aspects.

The project management triangle involves all nine knowledge areas in the project management knowledge system.

What is project management in PMBOK? In addition to the definition of PMI's authoritative project management, the rest is the triangle relationship. You can see the importance of the triangle relationship in project management.

Triangular relationship, that is, the relationship between project scope, project time and project cost, and the quality of the project is determined by the balance of these three factors. In terms of image, the project scope, time and cost are the three sides of the triangle, and the project quality is the area of the triangle.

To get a project product of target quality, the scope, time, and cost of the project must be determined. If any of these three changes, it is bound to affect at least one of the other two. The project is a project with manpower as the main cost. As the project team and the client reduce the budget cost in the planning stage to achieve a cost that is acceptable to both parties, the scope of the project, which is the complexity of the project, is inevitably greatly underestimated, so that 80 people are budgeted to complete the project in three months. And the cost of the project is calculated with staff hours. When the project started, due to the cooperation of the customer, the overall project progress was postponed for one month. This was what we were prepared for at the time, so it did not bring too much cost to the project. Two weeks after the problem started, when all the personnel were in place and carried out the specific work, we found that all the subordinate teams were facing a lot of problems of lack of resources. Although, in a short period of time, the missing personnel were brought together (already planned 3 times, reaching 240 people), but due to frequent staff changes and most of the additional staff are temporary staff, it is difficult to manage, resulting in a great delay in project progress, and this delay has been used for human resources. To the extent that it is impossible to keep the 240 people on this project indefinitely, at this time, the project fails, the project team conducts further negotiations with the client, and educates the client to accept the project results of the current stage.
